Abstract: A device having a receiving device for receiving at least one ribbon-shaped substrate and with a first and a second driving means, wherein the first and the second driving means for the transport of the ribbon-shaped substrate in x-direction are designed to cooperate such that the first driving means engages in the region of the one edge of the ribbon-shaped substrate and the second driving means engages in the region of the other edge of the ribbon-shaped substrate, wherein both driving means can be controlled such that they can drive the edge area of the ribbon-shaped substrate assigned to each driving means at adjustably different drive speeds. At least the first driving means is arranged in the device via a first displacement device allowing for a displacement essentially limited to the y-direction of the first driving means, relative to the receiving device.

Abstract: An ink supply system includes a print head assembly and a print head with one or more nozzles for a color. The print head is connected with the nozzles via a first connection line. A supply tank is connected with an intermediate tank via a filler line under an interconnection of a feed unit and a filter assembly. The pressure difference of the ink flow from a return tank to the supply tank is controlled by the print head. A method cleans the ink supply system, and a method cleans the print head.

Abstract: The invention describes an inkjet printer with a printing bed for displacing a print medium in a forward feed direction and a print head carriage disposed above the printing bed for displacing at least one print head unit in a transverse feed direction, a print head unit with at least one print head being provided for every color to be printed, each print head having at least one nozzle row oriented in the forward feed direction of the print medium. The nozzles of the at least one nozzle row of the print head unit are disposed offset from one another by a nozzle distance D by reference to the forward feed direction. Another print head unit is provided, which has nozzles in at least one nozzle row disposed offset from one another by a second nozzle distance d by reference to the forward feed direction of the print medium, the ratio derived from the nozzle distance D and the second nozzle distance d being a rational number and greater than 1.

Abstract: The invention relates to a method of producing a support (1) in the form of a prismatic hollow body and a support. The walls of the support (1) are formed by assembling top belt modules (2), bottom belt modules (3), front wall modules (4) and rear wall modules (5) respectively one after the other in the longitudinal direction of the support. Disposed in the interior of the support (1) at distances apart are transverse webs (6) and at least one guide track (7, 9) is provided on the support (1) extending in its longitudinal direction for a unit mounted so that it can move along the guide track. In order to obtain a high precision of the guide tracks (6, 7), the latter are formed by machining regions of the modules (2, 3, 4, 5) to remove material after the modules und transverse webs have been assembled.
